feat: Implement Statistics API with 8 endpoints under /api/v1/statistics/

- Add statistics.sql with 8 SQL queries for play count statistics
- Generate repository code via sqlc
- Add backend/statistics.go with business logic
- Add server/statistics_handler.go with Echo handlers
- Register protected routes under /api/v1/statistics/ with token auth
- Endpoints: games/most-played, games/least-played, games/never-played,
  games/last-played, games/oldest-played, songs/most-played,
  songs/least-played, summary
